Sustainable Construction: Constructors
Who should read this factsheet?
This factsheet complements the general sheet ’Sustainable
Construction: An Introduction’.
It has been written for organisations or individuals who work
on construction sites. This includes builders, trades people
and landscapers. It outlines the aspects of sustainability that
you should consider, why they are important and what you
can do to operate more sustainably.
Mini case studies towards the end of this factsheet show how
constructors are improving their performance.
Experience learned from employing more sustainable
practices can be used to improve the pricing of future
contracts and improve profit margins.
Environmental management. More and more clients are
requesting evidence of Environmental Management Systems
such as ISO14001 from constructors. For example, The
Environment Agency has undertaken a review of all its
contractors, asking them what systems they have in place,
and helping them to reach agreed standards.
Social performance. Clients are increasingly demanding
that contractors demonstrate higher levels of care and

Construction method. Careful consideration of the most
appropriate construction method, whether on-site or off-site
can contribute considerably to reducing construction costs.
Off-site fabrication can help reduce defects, which are a
prime cause of difficulties for constructors, and can also
reduce health and safety risks on site.

„ Scaffolding was avoided through modern construction
methods. This played a major role in the excellent
accident record on site.
„ A job centre located on site throughout most of the
construction phase facilitated the use of local labour. A
community liaison officer was also employed.
„ A balancing pond was constructed to capture run-off and
so reduce water pollution.
„ Features such as super insulation, natural ventilation and
solar shading together act to reduce the hospital’s energy
use by 30%. The extra insulation meant fewer radiators
were installed, saving capital cost.
„ The floor covering was chosen according to whole life cost
and environmental impact data.
